Abstract (en)
A building construction machine has a tracked vehicle chassis (2) supporting a horizontally pivoting platform (50). The platform has an upright mast (10) that is free to incline on a pivot (30) with respect to the vertical under control. The platform (50) with pivot (30) is free to slide longitudinally with respect to the chassis (2). The relative movement of platform to chassis is effected by a linear drive and does not pivot on the chassis. The linkage between the mast and platform is a universal joint. The platform incorporates an operator cabin and a hydraulic power supply system.
